Checker can read the barcode (ISBN) of a book with the camera of the Android device and display information about the book and information about the publisher. BOOKSCAN accepts only books whose copyright has expired, copyright-free books, books with the consent of the copyright holder, and books for which you own the copyright, and the copyright is valid at that time. For books that are not good, please check with this app, identify the copyright holder from the publisher information, contact us, and apply for BOOKSCAN with permission.

※Please be careful.
When you get the ISBN code, the book contains two barcodes. The barcode printed on the top is the ISBN code. Please read only the upper barcode by hiding the lower barcode by hand.

The number of volumes is just a guide. If there is a booklet, it will be +1 booklet.
